In Figure: Event Logging Block Diagram, the event sources are the main categories of events that feed the log manager.
Security — The security event source is all events that affect attempts to breach system security, such as failed login attempts, attempts to access MIB tables to which the user is not granted access, or attempts to enter a branch of the CLI to which access has not been granted. Security events are generated by the SECURITY application.
Change — The change activity event source is all events that directly affect the configuration or operation of the node. Change events are generated by the USER application.
Debug — The debug event source is the debugging configuration that has been enabled on the system. Debug events are generated by the DEBUG application.
Main — The main event source receives events from all other applications within the 7705 SAR.
